When we made the record, then it was “all we hear is radio caca”, because Roger wrote it - d'you know what “caca” is? If you have any French friends, “caca” means “shit”, so Roger wrote it because his little boy was saying, “it's caca, it's caca”, because he'd heard some grown-ups talking, so it was called Radio Caca, but our record company said, “you cannot do this! It has to be Radio Ga Ga”, which is the later lyric, so we changed the title but we didn't change the record, so if you go back and listen to Radio Ga Ga, you'll hear “all we hear is radio caca.” Nobody knows this, except you!
